The imaging method in non-penetrating deep sclerectomy (NPDS) was analyzed in 91 patients aged 43 to 89 years with primary open-angle glaucoma. Patients were divided into two groups by age and sex. Group I (n = 46) included the patients who underwent our modified NPDS and group II (n = 45) consisted of patients who were performed the classic NPDS by Fedorov-Kozlov method. After analyzing the data obtained, in group I, staining of juxtacanalicular tissue significantly improved visibility and made it easier to remove compared with group II. The study allows us to conclude about the effectiveness and safety of this visualization technique during surgery.
